Precious Metal Pd60Ag40-H04 vs Pd60Ag40-O
Precious Metal · Pd60Ag40 temper comparison
Pd60Ag40-H04 and Pd60Ag40-O are two conditions of the same precious metal grade, Pd60Ag40: H04 (full hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. Pd60Ag40-H04 is the stronger of the two: yield strength 680 MPa (98.6 ksi) against 180 MPa (26.1 ksi) for Pd60Ag40-O, about 3.8 times as much; tensile strength follows at 760 MPa (110 ksi) vs 415 MPa (60.2 ksi). In exchange, Pd60Ag40-O is the more ductile: elongation 30% versus 3% for Pd60Ag40-H04, and Pd60Ag40-H04 is harder (175 HB vs 80 HB). Pd60Ag40-O runs hotter in service (500°C vs 250°C continuous). On the shop floor, Pd60Ag40-H04 machines more easily (45 vs 35 out of 100) and Pd60Ag40-O welds better (very good vs good).
Pd60Ag40-H04Choose it when strength drives the design, or when the part is machined in volume.
Pd60Ag40-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Pd60Ag40-H04 vs Pd60Ag40-O: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all precious metal grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

Pd60Ag40-H04 vs Pd60Ag40-O — frequently asked
Is Pd60Ag40-H04 stronger than Pd60Ag40-O?
Yes. Pd60Ag40-H04 has a typical yield strength of 680 MPa (98.6 ksi) against 180 MPa (26.1 ksi) for Pd60Ag40-O — about 3.8 times as much. Tensile strength is 760 MPa (110 ksi) vs 415 MPa (60.2 ksi).
Which condition does FabDigit quote by default, H04 or O?
O is the default Pd60Ag40 condition in the FabDigit quote flow. The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, Pd60Ag40-H04 or Pd60Ag40-O?
Pd60Ag40-H04, by a small margin. Both rate fair for machinability — 45/100 against 35/100 for Pd60Ag40-O; for welding the order is Pd60Ag40-O first (very good, 75/100) then Pd60Ag40-H04 (good, 65/100).
